A) 2rad
B) 3 rad
C) 1 rad
D) 2 rad
Correct Answer: C
Solution :
As, angular width \[\theta =\frac{2\lambda }{d}=\frac{2\times 6000\times {{10}^{-1}}}{12\times {{10}^{-5}}\times {{10}^{-2}}}=1\,\,rad\] Note that the diffracted light is distributed in between, \[-\frac{\lambda }{d}\]to \[+\frac{\lambda }{d}\]You need to login to perform this action.
